A balanced incomplete block design (BIBD) [1] with parameters 2-(v, b, r, k, Î») (short 2-(v, k, Î»)) is a pair (V,B) where V is a v-set (elements are called points) and B is a collection of bâ€¦ (More)

Let GF(q) be the n-dimensional vector space over the Galois field GF(q). The Hamming distance between two vectors of GF(q) is defined to be the number of coordinates in which they differ. A q-aryâ€¦ (More)

We study codewords of small weight in the codes arising from Desarguesian projective planes. We first of all improve the results of K. Chouinard on codewords of small weight in the codes arising fromâ€¦ (More)

A classification of the doubles of the projective plane of order 4 with respect to the order of the automorphism group is presented and it is established that, up to isomorphism, there are 1 746 461â€¦ (More)
